Its then type that takes cannister refils,its not connected to a bottle,when you say "Yikes",i have only got a Norman 18 with 2 forward berths in cabin,thats where I make my tea,I never use the boat to sleep on,only for fishing and joyrides,as I am only 3 miles from the broads my bed at home is more appealing than sleeping afloat,however I have hired in the past from Richardsons,Aston Boats (now gone) and Swancraft,I would love to have a bigger and better boat with all the mod cons etc,but I am more than happy with what Ive got,only moan is its cold in the winter,hence the portable prezzie.
A Heater that don't work when its cold,chocolate teapot comes to mind
